Figure l is a perspective view of the cultivator; Fig. 2, a sectional "iew ofone of the plows.

This improved corn-cultivator Consists of two transverse parallel perforated beams, the" ter beam, for plowing on both sides of the corn at the same time.

Each plow consists of a mold-board, land side or bar, and share of the most approved construct-ion. To each bar of the plow is se cured a perpendicular stand ardor rod passing through a perforation in the mold-board, and secured to the forward parallet beam by screw and nut; also, another perpendicular rod extending from the heel of the laudside to the rear parallel perforated beam, throughwhich it passes for bracing and setting the plow, and an oblique brace extending from the heel of the mold-board through the last-mentioned beam. Both plows are furnished and arranged in a similar manner.

working between two rows only one horse may be used.

The distance apart of the plows may be regulated to any degree required by means ofthe rods of the plows and the perforations in the beams. p

This ClllLlVLt r nay be used for cultivating any kind of-plant to which itcau beappliedsuch as tobacco, cotton, rice, pease, beans, &c. The lower edge of the moldboard G rises from the point toward the heel at an angle of about ten degrees with the plane of the horizon. The edge of the other plow, G, is parallel with the plane of the horizon. The one kind (marked G).is for plowing between two ridges, and the other is for plowing a-flat surface. The angle, however, may be changed to suit the kind of plowing.

The invention claimed and desired to be seecured by Letters Patent consists- In the arrangement of the perforated beams, in. combiuation'with the shifting and reversible plows for throwing'the earth from or toward the rows of corn, regulated to any width required, in the manner before described.
